' SLIDING WINDOW Filed Sept. 1, 1931 2 Sheets-Sheet 2 r0 W7 W0 ww INVENTOR 0 0 elf/0mm flZWr- ATTORNEY Patented Mar. 6, 1934 UNITED STATES PATENT FFlCE This invention relates to laterally sliding windows and the frame therefor, beingan improve,- ment over my prior U. S. Patent No. 1,687,899, issued October 16, 1928. The object generally 8 stated, is the provision of inexpensively constructed and most efficient devices of this character having an exceedingly attractive appearance with adaptability to ready installation or removal of the individual sash.

More especially, it is a particular object of the present invention toprovide an assembly of a plurality of separable sash members wherein one of said sashes affords a screen, the arrangement being such that the screen member, while normally concealed, is adapted for ready introduction to a portion of the frame opening.

. A further and particular object of the invention is the provision of most efficient and simplifled latch structure interconnecting a window sash with the screen sash for controlling the movement of the latter, yet affording ready dislodgment of one from the other to afford an uninterrupted air passage, when desired, through a portion of the frame opening;

A still further object is the provision of most emcient mechanism, in structure of the character described, preventing admission of the elements responsive to adverse weather conditions.

It isa further and general object of the invention to provide an arrangement of sliding sashes and the frame therefor so designed as to most effectively afford ready removal of any or all of the sashes in affording an adjustment to the extent of the air passage through the frame aperture.

The foregoing, together with further and more particular objects and advantages, will, it is believed, become apparent throughout the course of the following description and claims, the invention consisting in the novel construction, adaptation, and combination of parts hereinafter described and claimed. 7

In the drawings:

Figure l is a front elevation of a portion of a building containing a three-sash window arrangement conformed in accord with the present invention, parts of the wall sheeting and siding being broken away to disclose the normally concealed screen in full lines.

Fig. 2 is a horizontal section thereof, taken on line 2-2 of Fig. 1.

. Fig. 3 is a transverse vertical section taken on line 3-3 of Fig. 1.

Fig. 4 is an enlarged detail fragmentary view 55 with the windowsill shown in section and representing the weather strip and drain arrangement.

Fig. 5 is an enlarged horizontal section taken on line 55 of Fig. 1, representing the latch interconnection between the window and screen sash and the weather strip in detail; and

Fig. 6 is an enlarged longitudinal vertical section, representing such latch interconnection.

, Reference being had thereto, introduced between upper and lower headers and frame jambs represented by the numerals 10, 11 and 12, the window frame proper comprises a head member 13, a sill 14, a stool 15' superposed over the rear portion of said sill, and vertical inner and outer sash jambs 16, 17.

The window trim encompassing the space formed between said sash jambs includes the conventional inner-casing 18, the apron 19 thereof, and the outer mold 20.

More particularly to the invention, said sill, the stool 15' being rabbeted for reception over the rear edge with its forward vertical face acting as a sash stop, is formed to provide an inclined facing surface 21, and with the front edge 22, constituting the window ledge proper, projecting in excess of the rearwardly stepped wing edges 23, each of the-latter of which project laterally within the spaces afforded between the outer house siding and the inner wall surfacing 24, 25.

Received in said sill forwardly'of the stool and co-extensively of the length thereof, I provide a tongue member 26, said tongue serving as a track rail and co-operating with a pair of laterallyspaced channel ways 2'7 grooved the length of the head member for slidably receiving the window and screen sashes S, S and S More particularly thereto, thelower and upper rails of said sashes are grooved the length of each to provide track ways, the lower seating over the aforementioned tongue member 26 and the upper received over the tongue member formed medially between the channel-ways 27, and. with the face of said lower rail, moreover, being inclined to the plane of the sill surface 21. Said sashes being of a height in excess of the space between said sill and head membersand slightly less than the space between said sill and the roof of the channel ways 27, the intervening space between the latter and the uppermost edge of the sashes, being determined by the height of the tongue 26, affords an introduction of the sashes by inclining the lower edges outwardly from the vertical, the sash being lifted to clear the tongue and subsequently lowered to receive the latter in the track-way therefor.

With respect to the aforementioned weather strips, I provide spring-metal members 28 having one leaf embedded in the outer surface of the lateral sash edges, the protruding portion facing directively of the stiles and preventing contact of the sash proper with the sash jambs. 31 represents drain passages emigrating below the stile members, said passages spilling from the frame edge 22 of the sill.

In the arrangement described, the sashes, the lateral edges of which are preferably of tongue and groove construction for interfit engagement, one with the other, are separably introduced in the manner described, a sash S and the window sashes acting as closures for the window aperture.

Looks for retaining the latter, as represented by 32, may be of any suitable construction.

As is believed evident, the screen sash may be drawn into the opening by sliding the sash S into the opposite enclosure, or as may be desired, sliding one of the window sashes and the screen sash S into respective enclosures to provide a space unrestricted by the screen. The ready removal of one or both of the window sashes from the frame affords an enlargement of the air space.

By reason of the reception, in its entirety, of the screen sash within the enclosure in its inoperative concealed disposition, it is extremely advantageous that means be afforded for withdrawing the same co-incident with lateral movement imparted to the window sashes. To such end, cut through the sash proper interiorly of the connection of the screen thereto, I provide a narrow vertically disposed slot 35, the opening of the same at the inner sash wall being in excess of the length of the arm 36 of a latch screw such as 37, the shank portion of which projects through the slot for engagement of the threads in the adjacent window sash. As represented, preferably utilizing the conventional angle thumb screw, the arm 36 in its normal disposition abuts the screen sash below the slot opening. Imparting a substantial 180 turnthereto allows a detachment of the two sashes by passing the screw head through the slot.

As represented, the screen sash is desirably formed to provide a tongue along both lateral sides to allow introduction of the screen at'either side of the window sashes.

The invention and use of the same is believed clear. However, beyond the limitations imposed by the scope of the hereto annexed claims, it is not my intention to in any way confine the same.
